SPECIFICATION forming part of Letters Patent No. 384,995, dated June 26,1888, Application filed January '7, 188 8. Serial No. 260,065. (Nomodel.)

To all whom it may concern.-

Be it known that I, STEPHEN F. Mooun, of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented new and 'of the completedevice.

useful Improvements in Carving-Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of said inven tion,reference being had to the accompanying drawings, and to the letters orfigures of reference marked thereon, which form a part of thisspecification.

My invention, to be hereinafter claimed, relates to the peculiar formand construction of the various parts of my mechanism and to thelocation, combination, and arrangement of those parts in the completedevice, in the manner and for the purposes hereinafter to be described.

In the drawings, Figure l is aside elevation Fig. 2 is a front elevationof the same device. Fig. 3 is a plan on line X X of Fig. 1 of theswinging arm and lower arm of the frame in which the cuttingtool iscarried and operated. Fig. 4 is a central vertical section of the jointconnecting the swinging arm and the thereon supported frame and ofadjacent parts of the mechanism. Fig. 5 is a central verticallongitudinal section of a portion of the arm of the frame that supportsand carries the carving-tool, with the carvingtool and its carrying anddriving mechanism in connection therewith. Fig. 6 is a detail of thedevice for adjustably securing the swinging arm to its supporting-hinge.Fig. 7 is an elevation of the guide in the upper arm of itssupporting-frame, a part being broken away to show interior parts.

The same reference letters and figures refer to like parts in all theviews.

The mechanism for supporting and operating the cutting-tool issupportedin brackets B and Osecured to a post, A, or studding of the building. Avertical shaft, 1, is supported and rotates in journal-bearings in thebrackets B and C. This shaft carries a fixed bandwheel, 2, whereontheband 3 runs which connects the mechanism with the power-supply.Aswinging arm, 4-, is supported by means of a pivoted hinge, 5, in thelower bracket, B. The arm 4 is so pivoted in the bracket B as to beadapted to swing horizontally through the entire are in front-of thepost A, and is adjustably secured to the hinge 5 by means of theset-screws G 6, turning through the slots 7 7 in the enlarged end of thearm 4 into the hinge 5, whereby the arm may be tilted from theperpendicular, either to right or left to a limited extent, as desired,wherebyI am able to get a proper alignment of the arm 4 and a certainamount ofunder-cut in carving, which is sometimes very effective,especially in figures in considerable relief.

Sometimes when heavy work is being done, and at all times, if desired, abrucc'rod, S, is secured at one end to a flange or bracket, 9, rigid onthe arm 4, and at the other end to a collar,-10, supported and movableabout the shaft 1. The rod 8 is inserted in the bracket 9 and collar 10by reverse screw-threads at its respective ends, whereby by its rotationit is loosened or tightened in its respective seats, and sufficient playis thereby provided for the tilting of the arm provided for in the adjustable bearings between the arm and binge 5. At its outer end the arm aon its upper surface is provided with an enlarged horizontal face, 11,whcreon is supported and swings horizontally the thereto-pivoted hinge12, having a corresponding bearing-face. This hinge 12 is integral withand a part of the upright standand 13. In front of the standard 13 andrigidly secured thereto is an upright p0st, 14,

which post is provided at its top and bet 1 tom, on both sides, withrecessed diamond shaped bearings 15 15, forming ways for supthetoolsupporting frame. This frame con- 8.. 3 porting and guiding thevertical movements of sists of the lower tool-carrying arm, 16, and i ofthe upper gnidecarrying arm, 17, which arms are rigidly connectedtogether, but at a distance apart, by the rods 18 18. This frame isprovided with adjustable bearings orguides the upper side of the lowerarm and against the lower side of the upper arm, respectively. Avertical alignment of this frame with reference to itssupporting-postljt may be secured by the adjustment of the guides 19 19in or out in their bearings in the arms 16 and 17, and securing themtherein by the set-screws 25, turning through the arms 16 and 17 againstthem. The outer end of the arm 16 terminates in a bracket or globelikeshield, 26, in which a small vertical shaft or spindle, 27, is supportedand journaled, which spindle in its lower end carries the carving-tool28. The bracket 26 is preferably constructed in the form of a sphericalshield having one side broken away, in which form it provides an upperand lower bearing for the spindle 27, and at the same time is a shieldfor the fixed pulley 29 on the spindle 27, and is adapted to serve as aknob or handle for the operator whereby to guide and manipulate thecarvingtool. The lower end of the spindle 27 is constructed as a chuck,split to receive the end of the tool 28 therein, which tool is held inposition by being clamped therein by the nut 30, turning on ascrew-thread on the spindle 27. To obviate friction, the spindle 27 isprovided with beveled bearings 31 3l,fitted into beveled hearings in theplug-nutjournals 32 32, turning in the bracket 26. For lubricatingpurposes the upper plug-nut journal 32 is pro vided with an oil-cup, 33,and an aperture therefrom through the plug-nut to the bearing of thespindle.

For driving the carving-tool a band-w heel, 34, is fixed on the shaft 1,and a belt, 35, running thereon, runs also on a band-wheel, 36, fixed ona shaft, 37, which shaft 37 is pivoted in the outer end of the swingingarm 4, and a pulley, 38, rigid on the shaft 37 carries a belt, 39, whichalso runs upon the pulley 29, fixed on the tool-carrying spindle 27. Anintermediate belt-t-ightening pulley, 40, supported and rotating on anarbor, 41, is located between the pulleys 29 and 38, and the belt 39runs on said pulleys 29 and 38, and runs also on the pulley 40, and isarranged to be guided and tightened thereby. For this purpose, and toget the greatest possible amount of adhesion of the belt 39 to thepulley 29,to avoid the slipping of the belt thereon, I preferably crossthe belt between the pulleys 29 and 40, as shown at 42. For the purposeof adjustment the arbor 41 is made adjustable in the arm 16longitudinally in the slot 43, in which the arbor is inserted, and towhich arm it is secured by means of a screw-threaded nut, 44. This arboris constructed of a central bolt, 45, a collar, 46, bearing on its uppersurface against the arm 16, and at its lower end beveled to receive acorresponding bearing of the pulley thereagainst, and a lower collar,47, also provided with a beveled upper end adapted to receive acorresponding beveled bearing of the pulley 40 and the two nuts 48 and44 at its respective ends.

It will be noticed that the diameter of the aperture through the centerof the pulley 40 is somewhat greater than the diameter of the bolt 45,and that the pulley is so constructed as to have bearings only on thebeveled ends of the collars 46 and 47, respectively, whereby the leastamount of friction is secured in connection with proper steadiness ofthe pulley.

Directly above the tool 28, and in the outer extremity of the arm 17, aguide, 49, islocated and adjustably secured. This guide is a small rodor spindle held upright in the arm 17, through which it is inserted. Forthe purpose of adjustment this spindle 49 is fitted nicely, but movablelengthwise, in a sleeve, 50,which sleeve at its upper end is providedwith a screw-thread, whereon a nut, 51, turns, which nut is adapted tobear against the top surface of the arm 17. The sleeve 50 at its lowerend is provided with a flange or head, 52, through which asetscrew, 53,turns against the spindle 49, and the diameter of the aperture throughthe arm 17 is somewhat greater than the diameter of the sleeve 50, butless than the diameter of the flange 52. By this construction thespindle or guide 49 may be adjusted vertically in the sleeve 50, andsecured in position by the setserew 53, and may be adjusted horizontallyin the aperture in the arm 17 and secured in place by the nut 51. Itwill be un derstood that the function of this guide 49 is to followtheelevations and depressions of a pattern placed immediately underit,whercby the movements of the tool 28 are guided up and down.

In the construction of thejoint between the hinge 12 and the arm 4 abolt, 54-, is inserted through the hinge 12 into the arm 4, which boltturns by a screwth read into and through a part of the arm 4, and isfurther secured in place by ajam-nut, 55, turning thereon. The upperpart of the shank of this bolt54 is provided with a beveled shoulder,56, adapted to receive a corresponding beveled bearing of the hinge 12thereagainst, and the diameter of the aperture through the remainingportion of the hinge-12 is somewhat larger than the diameter of theshank of the bolt 54, so as to reduce as much as possible the points ofbearing, and consequently the friction of the hinge 12 against the bolt54. A recess, 57, is provided in the surface 11 of the arm 4 forreceiving oil for lubricating purposes, and an oil-cup, 58, is securedin the top of the bolt 54, and a duct, 59, leads therefrom through thebolt 54 into the recess 57. The shaft 37 has beveled or conical hearingsin the lower end of the bolt 54 at one end, and at the other end in thebolt 60, turning through a part of the arm 4. For greater security thebolt is provided with ajam-nut, 61.

For supporting the material to be carved and the pattern for the work tobe done a tilt ing table in duplicate leaves D and D is located in frontof the swinging arm 4, and in proper position for the work of thecuttingtool and pattern in connection therewith. The part or leafD ofthe table is pivoted and supported on the uprights E E, which are partsof the frame E, which frameis supported and movable vertically on thesill F, which sill is supported in position by the legs F F.

For moving the frame E vertically a rotating shaft, G, is secured in itsunder surface,

which shaft is provided with a sere'w'thread turning in the bracket H,which bracket is rigid to the sill F. The shaft G is also pro vided witha pinion, I, meshing with a pinion, J, fixed on a shaft, K, supportedand rotating in a bracket, L, which bracket is fixed to the frame E. Theshaft K is provided with a hand-wheel, M, for rotating .it. The frame Eis guided in its movements vertically in ways in the guide'frame .N,which guideframe is affixed to the ceiling of the building. The upperleaf or table, D, is supported on and made a part of the lower leaf ortable, D, by means of the barsO, O, secured at their respective endspivotally to the lower and the upper table, I) and D, respectively. Theouter ends, P I, of these tables D and D are received between andguidedin their vertical movementsby the uprights of the frame E,aud aset screw, R, passing through aslot in the upright of the frame It, andturning into one of the connecting-bars 0, is adapted to secure thetables D and D in position as desired.

The material orblock S to be carved is placed on the table D, and thepattern T is placed on the table D directly above the block S. Thisblock S and pattern T may be clamped to their respective tables, ifdesired, for which purpose an ordinary wooden clamp, such as is commonlyused by carpenters and manufacthrough. the combined movements permittedby the swinging arm 1 and the thereon-hinged post 13, and thatsufficient vertical movement can be obtained in the vertical movementprovided for of the arms 16 and 17 on thepost 14.,
